实现拖拽到容器的基本步骤

使用Vue实现拖拽功能可以借助HTML5的拖放API或第三方库如vuedraggable。以下是两种常见方法的详细说明。

使用HTML5拖放API

HTML5原生支持拖放操作，通过draggable属性和相关事件实现。

<template>
  <div>
    <div 
      v-for="item in draggableItems" 
      :key="item.id"
      draggable="true"
      @dragstart="handleDragStart($event, item)"
      class="draggable-item"
    >
      {{ item.name }}
    </div>

    <div 
      @dragover.prevent
      @drop="handleDrop"
      class="drop-container"
    >
      拖拽到这里
    </div>
  </div>
</template>

<script>
export default {
  data() {
    return {
      draggableItems: [
        { id: 1, name: 'Item 1' },
        { id: 2, name: 'Item 2' },
      ],
      draggedItem: null
    };
  },
  methods: {
    handleDragStart(event, item) {
      this.draggedItem = item;
      event.dataTransfer.setData('text/plain', item.id);
    },
    handleDrop(event) {
      event.preventDefault();
      if (this.draggedItem) {
        // 处理拖拽逻辑
        console.log('Dropped:', this.draggedItem);
        this.draggedItem = null;
      }
    }
  }
};
</script>

<style>
.draggable-item {
  padding: 10px;
  margin: 5px;
  background: #f0f0f0;
  cursor: move;
}
.drop-container {
  padding: 20px;
  margin: 10px;
  background: #e0e0e0;
  border: 2px dashed #ccc;
}
</style>

使用vuedraggable库

vuedraggable是一个基于Sortable.js的Vue拖拽组件，简化了拖拽功能的实现。

安装依赖：

npm install vuedraggable

示例代码：

<template>
  <div>
    <draggable 
      v-model="draggableItems" 
      group="items" 
      @end="onDragEnd"
      class="draggable-list"
    >
      <div v-for="item in draggableItems" :key="item.id" class="draggable-item">
        {{ item.name }}
      </div>
    </draggable>

    <draggable 
      v-model="droppedItems" 
      group="items" 
      @end="onDragEnd"
      class="drop-container"
    >
      <div v-for="item in droppedItems" :key="item.id" class="draggable-item">
        {{ item.name }}
      </div>
    </draggable>
  </div>
</template>

<script>
import draggable from 'vuedraggable';

export default {
  components: { draggable },
  data() {
    return {
      draggableItems: [
        { id: 1, name: 'Item 1' },
        { id: 2, name: 'Item 2' },
      ],
      droppedItems: []
    };
  },
  methods: {
    onDragEnd() {
      console.log('Drag ended:', this.draggableItems, this.droppedItems);
    }
  }
};
</script>

<style>
.draggable-item {
  padding: 10px;
  margin: 5px;
  background: #f0f0f0;
  cursor: move;
}
.drop-container {
  padding: 20px;
  margin: 10px;
  background: #e0e0e0;
  border: 2px dashed #ccc;
  min-height: 100px;
}
</style>
